Contradictory results have been reported regarding the accuracy of various methods used to assess student learning in higher education. The current study examined student learning outcomes across a multi-section and multiinstructor psychology research course with both indirect and direct assessments in a sample of 67 undergraduate students. The indirect method measured student perceived knowled...

In this paper, a simple and reliable procedure of stochastic computation is combined with the highly accurate and efficient Trefftz Computational Grains (TCG), for a direct numerical simulation (DNS) of heterogeneous materials with microscopic randomness. Material properties of each material phase, and geometrical properties such as particles sizes and distribution, are considered to be stochas...

In the previous six chapters, we have discussed the application of T-elements to various linear problems. This approach can also be used to solve both geometrically [8-10,12] and materially [1,18] nonlinear problems. The former are treated in this chapter and the latter are addressed in Chapter 8. The first application of T-elements to nonlinear plate bending problems was by Qin [8], who presen...

A new approach called the“Variational Theory of Complex Rays”has been developed in order to calculate the vibrations of slightly damped elastic plates in the medium-frequency range. The solution of a small system of equations, which does not result from a fine spatial discretization of the structure, leads to the evaluation of effective quantities (deformation energy, vibration amplitude,. . . ...
